Yes or No.

So we all agree the "elevates" are in Tsavo, then the embankment are a means to the elevates/overpass. Why has the embankments continue all the way to Athi River? Then in Athi River there is another overpass then more embankments mpaka Syokimau Nairobi station? My question is very simple, even a class 7 Homescience pupil will agree that you dont a whole 450km to descend a 10m cliff/elevate. My question still remain, why did the designers elevate the railway above the ground between 5m to 10m the entire length...a whole 500km for a train struggling to maintain 80km/h speed?Portfolio: Sold

Tsavo stretches from Samburu up to Kibwezi. About 200+ Kms the next one is just b4 Athi river Take time and visit the site first, at this rate it will a waste trying to explain anything SGR to you. You still believe one of the reason the entire track is elevated 10m is coz this will enable it carry heavier loads...abject stupidy! By the way come to think of it,the elevation (by compacting soil) in the Tsavo will only prevent larger animals like Elephants, Girrafe etc from closing...anything in the size of hyena,cheetah,dik dik etc will easily climb the 10m walls...including human beings. But what gain is there for elevating it in the sparsley populated areas devoid of appreciable wildlife like the Yatta plateau? What gain? Portfolio: Sold

@Guka, You dont belong to shouting matches,you belong to giving us wisdom.Hii maneno wachana nayo,with due respect to both of you. Advice is like snow.The softer it lands the harder is sticks.

I do believe @impunity is an Engineer and a good one at that, anyone reading this thread and following a history of his none sexist posting would know that. Its unfortunate that him and Guka don't mix coz I happen to think the @Guka is also very knowledgeable on matters Engineering and manufacturing if I remember correctly. There must be some good reason why the Chinese elevated the railway, we don't know and we should may be research. This reminds me of road building, the chinese use soil while our Kenyan contractors try and crush stones, we know whic roads last longer. P.S. I am not sure where exactly the wildlife corridor is at along Nairobi Mombasa Road, I thought it was just a short span past Voi (towards Mombasa) the rest of the road hamna crossing ya animals between Tsavo East & West. I 'm I right? "The purpose of bureaucracy is to compensate for incompetence and lack of discipline." James Collins

Mimi nko na swali mbiri pekee yake 1. Is it true that the whole Msa-Nairobi section is elevated(485Kms) 2. if true, why is the whole section elevated unlike only elevating where there is a wildlife corridor, dense population, rivers, road crossing, valleys, hills etc? If Obiero did it, Who Am I?

I have been there, and if the engineers on site figured that an elevation is best why should you a useless fella argue with it? They can elevate it everywhere, kwani wewe tu ndio utalipia? Sit down and watch it as it happens.     Mombasa West    Is this your problem?  Huku ndio ulifika?  "There are only two emotions in the market, hope & fear.

THE ENTIRE 500KM IS ELEVATED, TAKE THIS TO CBK.A few sections are elevated using the white (no pun for white elephants) concrete beams, but the rest are on a raised platform made from compacted soil/murram, as high as 10m in some sections. Elevating the entire length is very expensive (ata kama mchanga ni free) and we must get the reson why they decided on that, plus its an ugly "greatwall" sepataing two sides of a quiet countryside. Try driving on sections parallel to th SGR and you will be treated to a compacted wall on one side of your view, the entire journey until a point of deviation. Those of us who occasionaly use the LUNATIC LINE to Mombasa will agree with me that the once lavish and beautiful Savannah view is greatly obstracted. If they thought elevating it will prevent wild animals and walevi from crossing the line then they failed...they will need a nother 50 billion shillings to fence it. Portfolio: Sold
